NOTE ON DIAZOSMA (TBICHOCEBA) HIBTI/'ENNIS, Siebke. 

 BY J. E. COLLIN, F.E.S. 



This species stands in the Palaearctic Catalogue under the generic 

 name Diazovna, Walleng., but this name being preoccupied in the 

 Mollusca, Bergroth (Ann. Mag. Nat. Hist,, 1913, p. 583) has changed 

 it to Diazosma. The female ovipositor, composed of small fleshy- 

 pubescent lobes, is so completely different to the chitinous pointed 

 ovipositors of Trichocera that the doubts expressed by Osten-Sacken 

 (1887) as to the generic distinctness of the species may well be con- 

 sidered as removed. It has previously been recorded from only Norway 

 and different parts of Austria. Mr. Kirkpatrick has very kindly 

 allowed me to add the above British specimen to my collection.

CMonotopus, an unrecorded genus of Coleoptera. — Owing to a curious mistake 

 on the part of its author, Abeille cle Perrin, the genus CMonotopus has been 

 overlooked and is not found in any of the successive issues of the " Nomenclator 

 Zoologicus." 



In 1891 he described the genus CMonotopus (Ann. Soc. ent. France, 60, 

 p. 179) and there stated that he had named and described the genus in Ann. 

 Soc. ent. France, 1881, p. 125. This, however, he had not done : he there merely- 

 described two species as MalacMus damascenus and mossulensis, and says not a 

 word as to their being a distinct genus, but at the bottom of p. 126 he says he 

 thinks it may be a distinct group to be separated from MalacMus and called 

 CMonotopus. The reference for this name will therefore be " Abeille de Perrin, 

 Ann. Soc. ent. France, 51, 1881,p. 126."— D. Sharp, Brockenhurst: Sept. 22nd, 1914 



Criocephalus ferus, Kraatz, at Oxford. — On August 21st my friend Mr. T. 

 Trollope, of Summertown, Oxford, said he had a " curious beetle " to show me. 

 Not expecting anything rare, I was surprised and pleased when the insect was 

 produced, to find that it was a fine and perfect living $ specimen of Criocephalus 

 ferus, Kraatz, a very welcome addition to the local list of Coleoptera. The 

 beetle was taken by Mr. Trollope's daughter on August 19th, on a window- 

 curtain in his house, and must have come from some distance, as there are very 

 few pine-trees in the neighbourhood of Oxford in which it may have bre'd. —
